Hosta plant named ‘Party Streamers’

ABSTRACT

A new and distinct Hosta plant named ‘Party Streamers’ with medium, rounded-mound habit of arching chartreuse foliage. Leaves are long and narrow with wavy margins. Flowering begins in late July through late August with tepals opening wide to show strong violet coloration with darker veins. Seed pods take on purplish-red coloration when developing in high light conditions. The new plant is attractive for landscaping in the garden as a specimen, in mass and as a container.

Latin name and variety denomination of the plant:

Botanical classification: Hosta hybrid.

Variety denomination: ‘Party Streamers’.

STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(B)(6)

Hosta ‘Party Streamers’ was first introduced by the inventor as a non-enabling description through the International Cultivar Registration Authority registration in early 2020. No plants of Hosta ‘Party Streamers’ have been sold, in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior the filing date of this application.

BACKGROUND AND ORIGIN OF THE PLANT

The present invention relates to a new and distinct Hosta plant, Hosta ‘Party Streamers’ hereinafter also referred to as the new plant or just the cultivar name, ‘Party Streamers’. Hosta ‘Party Streamers’ was single seedling selection from a cross on Aug. 23, 2013 by the inventor at a wholesale perennial nursery in Zeeland, Mich., USA between ‘Atom Smasher’ (not patented) as the female parent and the non-patented, unreleased, proprietary hybrid known only as ‘11-463-02’ (not patented) as the male parent. The new plant was assigned the breeder code 13-443-4 and passed the initial evaluation in the summer of 2016. The new plant has been asexually propagated by division at the same nursery in Zeeland, Mich., USA since 2017 and also by careful plant shoot-tip tissue culture with the resultant asexually propagated plants having retained all the same traits as the original plant.

BRIEF SUMMARY OF THE PLANT

There are over 7,000 registered and unregistered Hosta cultivars recognized by The American Hosta Society, which is the International Cultivar Registration Authority for the genus Hosta. The nearest known comparison cultivars are the female parent, ‘Atom Smasher’, ‘Bitsy Gold’ (not patented), ‘Cricket’ (not patented), ‘Curly Fries’ (not patented), ‘Munchkin Fire’ (not patented), ‘Pineapple Juice’ (not patented), ‘Surfer Girl’ (not patented) and ‘Wiggles and Squiggles’ (not patented).

All of the above plants have a lanceolate leaves with undulate margins. ‘Atom Smasher’ is smaller in height, the foliage is less arching, and the flowers are not as purple. ‘Bitsy Gold’ is smaller in habit, with smaller foliage that is more yellowish and lacks the undulation. ‘Cricket’ is about half the size in habit with smaller foliage that has a cordate base, and the proportion of blade width to length is greater. ‘Curly Fries’ has a larger habit with smaller, longer and narrow leaves with less reddish stippling in the petiole and the undulation decreases with maturity. ‘Munchkin Fire’ has a smaller habit with smaller shorter leaves that are more yellowish. ‘Pineapple Juice’ has a larger habit, but the growth rate is slower, the foliage is lighter yellow, and the petiole has much less reddish stippling. ‘Surfer Girl’ has smaller habit with shorter foliage that has a cordate base and the flowers are paler purple. ‘Wiggles and Squiggles’ has a larger habit, the foliage is lighter yellow with less reddish stippling in the petiole and flower scape.

The male parent was less yellowish in foliage and had a larger habit.

Other Hosta cultivars have similar colored foliage, but ‘Party Streamers’ is distinct from the above listed Hostas and all other cultivars known to the discoverer by the following combined traits:

-   -   1. Medium-sized, round-mounded plant habit with arching         chartreuse foliage;     -   2. Leaves are long and narrow with wavy margins;     -   3. Medium-sized flowers droop downwardly from erect scapes well         above the foliage;     -   4. Tepals are strong violet with darker veins and vitreous or         transparent margins.     -   5. Seed pods display a purplish-red while developing.

Ambient light spectrum, temperature, source and direction may cause the appearance of minor variation in color.
